A glossy brochure, a sea-view terrace and a respected developer are excellent reasons to feel confident about an off-plan purchase. They are not, however, a substitute for inspecting the finished home with care. Knowing how to inspect new builds gives you the chance to spot defects before completion, protect your investment and start life in your new Costa del Sol home on the right foot.
For buyers purchasing from overseas, the process can feel especially remote. Construction updates can look impressive, but photographs can’t reveal an uneven floor, a poorly fitted window or air conditioning that hasn’t been commissioned properly. A careful inspection turns anticipation into certainty. For the full sequence from reservation to keys, read a guide to buying new developments in Spain.
Start inspecting before the handover date
The most effective inspection isn’t limited to one visit with the keys on the table. If your purchase stage allows it, arrange to see the property during construction and again shortly before completion. Early visits help you understand whether the home is progressing in line with the agreed plans, specification and orientation that influenced your decision to buy.
This is particularly valuable in developments where views, privacy and sunlight are central to the appeal. In an elevated community in Benahavís, for example, a terrace may enjoy a very different outlook from the one suggested by an early site plan once neighbouring phases, landscaping and boundary treatments are complete. In coastal areas such as Estepona or Casares, visit at different times of day where possible to assess wind, traffic, sun exposure and noise.
Ask for the latest plans and specification before each visit. Developers can make permitted changes for technical or supply reasons, but those changes should be transparent and should not materially diminish what you contracted to purchase. Compare the layout, built-in furniture, kitchen design, bathroom finishes, appliances and exterior elements against the documentation rather than relying on memory.
Bring the right expertise to the inspection
A new home should look immaculate, but cosmetic presentation is only one part of the assessment. A professional snagging inspection by an independent technical specialist can be a prudent choice, particularly for a high-value villa, penthouse or second home that won’t be occupied immediately.
The inspector’s role isn’t to create friction with the developer. It’s to document visible defects, incomplete works and items that don’t appear to meet the agreed standard. They may use tools to check levels, moisture, thermal performance and the operation of installations that a buyer wouldn’t reasonably test alone.
Do you always need one? It depends on the property and on how confident you feel. A compact new apartment from a developer with an excellent completion record may only need a focused visual inspection. For a substantial villa with a pool, a landscaped plot, smart-home controls and multiple terraces, I’d recommend a more detailed technical review. The cost of a professional inspection is often modest next to the inconvenience of resolving defects after the furniture has arrived and the property is in use.
How to inspect new builds room by room
Take your time. A handover appointment can feel celebratory and, understandably, buyers often want to move quickly towards completion. Treat it as a working visit instead. Take photographs and videos, record each issue clearly and note its precise location. A snagging list that says “marks in bedroom” is easy to overlook; “two paint marks and a hairline crack on the wall beside the en-suite door in bedroom two” is actionable.
Begin with the fundamentals. Check that internal doors open, close and latch smoothly, and that handles, locks and wardrobe doors are aligned. Look along walls and ceilings in natural daylight for cracks, rippling plaster, inconsistent paintwork or visible joints. Minor settling cracks can occur in new construction, but they should still be recorded and reviewed.
Inspect floors from standing height and close up. Tiles should be consistently laid, free from chips and hollow sounds, with clean grout lines and properly finished edges. Wood or laminate flooring shouldn’t flex, separate or show damage near thresholds. In bathrooms, look carefully at the sealant around showers, baths and basins, where incomplete finishing can later become a water-ingress issue.
Kitchens deserve a methodical check. Open every cupboard and drawer, inspect worktop joins, run the taps and confirm that the appliances in the specification are present and working. Check for leaks below the sink and make sure extractor hoods, oven controls and integrated appliances have been connected and tested.
Don’t overlook windows and external doors. They should glide without force, lock securely and show no damage to frames or glazing. On the Costa del Sol, effective seals and drainage channels matter as much as appearance. Even in a climate known for sunshine, intense rainfall and wind can expose weaknesses around terraces, rooflines and large sliding doors.
Test systems, not just finishes
A premium new build is often defined by its systems: underfloor heating, air conditioning, aerothermal hot water, home automation, security, irrigation and, in some communities, electric vehicle charging. Ask the developer or site representative to demonstrate each installed feature rather than accepting that it will be explained later.
Run every tap and flush every WC. Check water pressure, hot-water response and drainage. Switch lights on and off, test sockets where it’s safe to do so, operate shutters or blinds, and ask to see the controls for heating and cooling. If the property includes a smart-home system, establish exactly what it controls, which applications are required and whether any subscriptions or third-party accounts will pass to you.
For villas and ground-floor homes, give particular attention to outdoor areas. Confirm that terraces drain away from the property, exterior lighting works and irrigation points are accessible. If there is a pool, establish who has commissioned it, whether the filtration and lighting have been tested, and what maintenance information you’ll receive. A beautiful pool is a defining lifestyle feature, but it also needs a clear technical handover.
Check the development beyond your front door
Your home is only part of the purchase. In a gated development, shared areas affect both your daily experience and the long-term appeal of the property. Walk the route from the parking space or garage to the residence. Check entrances, lifts, corridors, storage rooms, landscaping, lighting and any communal facilities promised in the sales material.
If the development includes a gym, spa, co-working space or communal pool, ask whether it is complete, operational and available from handover. Phased projects require a realistic view of what remains under construction. Future phases may enhance the community and support value over time, but they can also mean temporary noise, construction traffic and limited access to certain amenities.
Before completion, make sure you’re clear on the documentation and arrangements that support the property. In Spain, that normally includes:
- the first occupation licence (licencia de ocupación) and the certificado final de obra;
- the libro del edificio (building book) and the energy performance certificate;
- proof of the ten-year structural insurance (seguro decenal);
- the final specification and any agreed variations;
- operating manuals, guarantees and appliance information;
- keys, remotes, access cards and garage controls;
- community details, anticipated running costs and administrator contact information;
- the procedure and timeframe for reporting post-completion defects.
A reputable developer should provide an organised handover pack. Keep digital copies as well as physical documents, particularly if the home will be used as a holiday residence or managed from abroad.
Understand snagging and warranty responsibilities
Snagging is the process of identifying work that is incomplete, damaged or below the agreed finish. It’s normal in new construction and shouldn’t be confused with a structural concern. The key is to record issues before completion where possible, agree how they will be corrected and keep written confirmation of the developer’s response.
Spanish new-build homes also benefit from statutory building guarantees under the building law (LOE): one year for finishing defects, three years for defects affecting habitability and ten years for structural damage. These protections are valuable, but they’re not a reason to postpone a thorough inspection. A visible issue is generally easier to resolve when the developer’s contractors are still on site and the development team is still actively involved.
Be reasonable as well as precise. A tiny paint touch-up is different from a misaligned sliding door or a terrace drainage problem. Prioritise safety, water ingress, installations, locks, glazing and defects that could worsen or affect your enjoyment of the home. Then make sure the smaller finishing items go on the same written list.
Don’t let completion pressure rush your decision
Completion dates can involve travel arrangements, mortgage deadlines and the understandable desire to receive the keys. Even so, don’t let a hurried appointment stop you from raising legitimate concerns. If significant defects are found, seek professional legal and technical advice on the appropriate next step under your contract.
The best new developments combine refined design with the practical quality you’d expect from a lasting home. A careful inspection protects that standard. It also lets you step onto your terrace, open the doors to the Mediterranean light and enjoy the property for what it was meant to be: a place of complete confidence, not a list of jobs waiting to be done.
